Polar substituent effect of the ester group on conformational equilibria of O-mono-substituted cyclohexanesùthe para-substituent effect in cyclohexyl benzoates

  • Together with the nonsubstituted reference compound, para-methoxy- and para-nitro cyclohexyl benzoates have been synthesized and their conformational equilibria studied by low temperature NMR spectroscopy and theoretical DFT calculations. The free energy differences ;G° between axial and equatorial conformers were examined with respect to polar substituent influences on the conformational equilibrium of O-mono-substituted cyclohexane.
